Disturbing new details emerged on Saturday about the FBI's investigation into allegations that Dr. Larry Nassar was sexually molesting girls while the bureau was led by former FBI director James Comey.

The FBI reportedly dragged its feet in the investigation, moving with "little evident urgency," which led to dozens of additional victims who claim they were sexually molested by Nassar during the FBI's investigation. The New York Times reports:

The New York Times has identified at least 40 girls and women who say that Dr. Nassar molested them between July 2015, when he first fell under F.B.I. scrutiny, and September 2016, when he was exposed by an Indianapolis Star investigation. Some are among the youngest of the now-convicted predator’s many accusers — 265, and counting.

The three alleged victims then at the center of the F.B.I.’s inquiry were world-class athletes; two were Olympic gold medalists. Nearly a year passed before agents interviewed two of the young women.
